Re: Wire Wheels: Restoration
Hi Dave,
There are many types of media used in blasting, depending upon the item being cleaned and what needs to be removed. Amoung the milder forms of media are plastics and walnut shells. Soda is also used. Glass beads might be used on some items.
Talk to a local shop, let them know your concerns and see what they recommend. Many are equipped to do different types of blasting and can handle a wide variety items.
Media blasting would be far faster, more thorough and effective than hand sanding could ever be. Done right, it gives a perfect "tooth" for paint or powder coat.
I also hate to see a paint stripper used in a job like this. There are so many tiny hiding places for the stripper, that some is almost sure to survive any and all cleaning. It's almost inevitable that some will seep out eventually to ruin the new paint job.
Regarding powder coating wire wheels, I'd not recommend it unless they are disassembled (which probably would mean relacing with new spokes). If powdercoated as a unit, the spokes will be impossible to adjust without damaging the finish. That would mean refinishing the entire wheel and most powder coatings are so tough that a very caustic sort of paint remover is needed to do that job.
IMHO, the easiest way to recondition a set of wire wheels would be to prep the wheels with media blasting and spray with a couple nice thin coats of paint. The "right" (but impractical) way would be to disassemble completely, refinish the parts individually and rebuild the wheels with new spokes.
